JAR-CLOSURE.

SPECIFEGATION forming part of Letters Patent No. 676,774, dated June 18,1901.

Application filed February 23, 1901. Serial No, 48,582. (No model.)

To all whom it may concern:

Be it known that I, ELIZA SOHIFFERLY, a citizen of the United States,residing at Fort W'ayne, in the county of Allen and State of Indiana,have invented a new and useful Jar- Closure, of which the following is aspecification.

vThis. invention relates to jar-closures, and has for its object toprovide an improved device of this character which is especially adaptedfor fruit-jars, so as to hermetically seal the same, and at the sametime facilitate the application and removal of the closure.

With these and other objects in view the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanying drawings, and particularlypointed out in the appended claim, it being understood that changes inthe form, proportion, size, and minor details may be made within thescope of the claim without departing from the spirit or sacrificing anyof the advantages of the invention.

In the drawings, Figure 1 is a perspective View of the top portion of afruit-jar having the improved closure applied thereto. Fig. 2 is avertical central sectional View thereof.

Like characters of reference designate corresponding parts in both ofthe figures of the drawings.

Referring to the drawings, 1 designates the body of a fruit jar or canwhich has a flat top 2, that is provided with a marginal depres sion 3,forming a seat for the reception of a suitable packing-ring 4E. Theopposite side walls of the depression or seat are parallel, and theinner wall 5 rises to a suitable distance above the top of the jarandforms a flange surrounding the mouth or entranceopening of the jar. henthe jar is formed of tin or other metal, the top 2 is a ring secured tothe top edge of the body. The bottom and outer side of the seat ordepression are formed from a single ring of sheet metal, having itsouter portion bent upwardly, so as to form an upstanding marginal outerflange which has its upper edge connected to the top of the can. Theflange 5 is also formed of a single upstanding band which has its loweredge connected to the inner edge of the ring that forms the bottom or".the packingring seat.

The closure proper is in the form of a hollow cap 6, having a flat topand a pendent outer marginal rim 7, that is designed to snugly embracethe upstanding flange 5, there being an outwardly-directed marginalflange S at the bottom edge of the rim to rest upon the packing-ring.

For fastening the closure or cap against accidental displacement fromthe jar there is provided the diametrically opposite fastening devices9, which are duplicates in construetion and mounting, and therefore adescription of one will be sufficient. Each fastening is in the form ofan open link formed from a single piece of stiif wire which is bentintermediate of its endsinto substantially U shape, and then the sideportions of the link are bent in the same direction, so as to produceangularly-related end portions. The opposite terminals of the wire arebent laterally inward in opposite directions to form the respectivepivot-pins 10, which are sprung into the opposite ends of a bearingsleeve or eye 11, secured to the top of the cap and at the outermarginal edge thereof. In the locked position of the fastening-link thevertex of the angularly-related end portions thereof fits snugly theupper marginal edge of the jarbody, while the free end portion of thelink lies against or in close proximity to the outer side of the jar,the transverse end of the fastening snugly embracing a lug or projection12, carried by the side of the jar, the link being sprung intoengagement therewith, so as to more tightly draw the flange of the capdownwardly against the packing-ring to hermetically seal the jar. Itwill be observed that the upper and outer side of the keeper formed bythe lug or projection is inclined or beveled downwardly and outwardly,so that the free end of the fastening may ride over the projection whenthe cap is being forced downwardly. The fastenin'gs may be convenientlysnapped into locked engagement with the lugs by placing one hand acrossthe top of the jar and pressing downwardly upon the angular intermediateportions of the fastenings with the tops of the fingers and the base ofthe palm of the hand, respectively.

To facilitate the application of the cap and also the removal thereofafter the fastenings have been disengaged from the jar, the saidfastenings are swung upwardly and inwardly oted to the upper marginaledge of the cover, each fastening having an inner end portion inclineddownwardly and outwardly to the outer top edge of the jar, and an outerend portion pendent from the inner portion and constructed to lie flatagainst the outer side of the jar and to engage the adjacent projectionthereon, the point of intersection of the opposite end portions of thefastening forming a seat constructed to snugly embrace the edge portionof the jar.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

ELIZA SCHIFFERLY.
